TruDesign Ball Valves are designed and made in New Zealand for use in marine applications above and below the water line.
The body of the Ball Valve is manufactured in glass-reinforced nylon composite with high impact and tensile strength resulting in a light weight unit, free from corrosion and electrolysis issues. The ball and sealing rings utilise a PTFE polymer to ensure a smooth action, and continuous ease of operation over many years.
